Is it possible to worry to much about cleaness?

I heard an interesting report on TV today about how clean a person should keep things in their house.  I've heard similar reports before and I do try to live a clean life, within reason. I do vaccuum and dust fairly regularly and of course I run the dishwasher and put out the garbage. I even recycle, and occasionally wash a window. My bathrooms are clean and I swiffer my tile floors sometimes (especially if company is coming). I did wonder though about some things on the report this evening. One question they asked was how often should you wash your pajamas? They said the average time in a survey is every 17 days but the reporter suggested every 3 days is better. What they didn't say in the report was how many pairs of pajamas we're talking about here. One pair of pajamas worn for 17 days sounds disgusting but if you have 17 pairs of pajamas and wash them all together every 17 days that sounds pretty clean to me. I personally wash all of my clothes every 14 days but that doesn't mean I wear them for 14 days.  They also mentioned that the TV remote control is one of the germiest surfaces in the house and should be wiped frequently with antibacterial wipes. Personally I don't put my remote in my mouth so I'm not too worried about this. One mroe thing. She said bathroom hand towels should only be used for one day. That's ok with me if you want to do it but I didn't appreciate the suggestion that we should use disposable hand towels.  Seems to me that just adds to the polution problem.  Ah well, I guess I'll just go to bed (in pajamas that have not been worn for 17 days) and worry about all this tomorrow.
